MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 572,712, dated December 8, 1896.

A li ation fil d October 17, 1895. Serial No. 565,940. (No model.)

To all whom it mag concern:

Be it known that we, OLAUS OLSON, a subject of the King of Sweden and Norway, and J OHAN AUGUST J OHANSON, a citizen of the United States, both residents of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Merry-Go-Rounds, of which the following is a specification.

The invention consists of improved merrygo-round apparatus comprising two or more horizontal rotating platforms and other adjuncts moving in opposite directions, as hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is a sectional elevation of our improved apparatus, which is indicated in this example as of diminutive size, as it may be made for a toy or for display purposes in show-windows; but it is intended also for larger sizes adapted for the general purposes of such contrivances. Fig. 2 represents plan views of parts in different horizontal planes indicated by line 2 2, Fig. 1. Fig. 3 is a detail on section 3, Fig. 1.

A represents a stationary floor surrounding a circular space in which is an annular rotating platform 1), within which is a central rotating disk 0, all in the same horizontal plane.

The floor A is supported on the curb, or it may be a wall d, extending above a floor e and inclosing a chamber f, below which is another chamber, or it may be a pit g in the ground. From the center of the floor h of the chamber or pit g a stationary shaft 71 extends upward a suitable height, said shaft being secured by a nut j, screwed on it below, and ashoulder 70, hearing above the bed-plate Z, resting on the floor h. A sleeve m, surrounding this shaft and extending from the lower end to a suitable height above the disk 0, is employed for sustaining the Wear of the operating parts centered on the shaft, said sleeve being readily removable for renewal when required, thus saving the renewal of the shaft if subject to the wear, which would be more expensive.

The annular platform I) is carried on the rotating spider n, whereon it is supported by the standards 0, and the spider is carried on the hollow shaft 19, having a step-bearing at q in the hub s of the bevel-wheel 1, having its support on the bed-plate Z. The sleeve 19 also carries a bevel-wheel u, these two wheels being geared with the bevel-pinion 'v on the driving-shaft w, so that they revolve in opposite directions. From the hub s of wheelt a hollow shaft 50 extends upward within shaft 19 and surrounding sleeve m and carries the spider 3 above spider n and carrying the disk 0, said disk and platform I) turning in opposite directions correspondingly .With the reverse movements of Wheels 25 and u. r

V Carrying rolls 2 are arranged between spider n and floorcto relieve the shaft 19 of the weight, said rolls having axles a radiating from a collar b on shaft 19 and at the outer extremities connected with a ring 0. The spider n has ring-rails d bearing on the rolls. The collar 1) is adapted to turn independently of the shaft 19. Spider y is in like manner supported on carrying-rolls e by ring-rails f, said rolls being similarly mounted on radiating axles g of a collar h and connected at the outer ends with a ring 71, and the spider n has rails j for supporting the rolls 8'.

The platform I) and the disk 0 are provided with various forms of benches, seats, or other devices for carrying riders, as persons or figures or goods, some of which may be constructed in the form of boats 70', which we provide with a keel-like support Z, pivoted in the platform at m and extending downward therefrom at n to and suitably connected with a sinuous guide-rail 0' on the floor e, by

which rocking motion is imparted to the boats when being carried on the platform. The diskc carries one or more wheels 13 with a seat q in suitable relation to it to represent in some measure a velocipede, the wheel being pivoted at s and rolling on a rail 25', carried on the spider n. Said disk also carries a series of horizontal disks u, located in a circle around the center shaft and geared by chains 22 with the stationary sleeve m, so that as they are carried around the shaft of the disk they will also be rotated on their own axis by the chains. The said disks are preferably inclosed in curbs w, and they will in practice have seats or be otherwise adapted for carrying figures for exhibition or persons for pleasure.

From the center of each disk u a vertical shaft m extends upward to a bearing in an arm y, projecting from a collar 2, adapted to turn on shaft '1; in unison with the movements of the shafts 00" around shaft t', and these shafts a? are geared with shaft i by belts a and pulleys b so as to be rotated 011 their own axis also, and they are preferably arranged to rotate reversely to the directions in which the disks u rotate. The collars c on the shaft 2' keep the belts to in position and prevent them from interfering with each other.

The shafts cc are each provided with a sunshade or umbrella top f for ornamentation. The upper end of the center shaft iis stayed by braces g and posts h the latter being set up on the permanent floor A, and the posts 7L2 are coupled by a ring 1' at the top for stability.

hen constructed in small sizes for toy or show purposes, handles of any approved kind,

as staples of round iron j will be attached to the base k for convenience in moving the apparatus about, and said handle maybe applied so as to be shoved inward out of the way when not in use, the inn er ends of the prongs having nuts Z or other stops to limit.

their projection outward for use. In this example we represent a crank m as the means of turning the driving-shaft w, and indicate a detachable connection at n for removal of the crank as a protection against unauthorized use.

0 represents a bell carried by one of the standards 0, and p a hammer carried by another of said standards, with a spur g of the curb d to raise the hammer and cause the bell to be struck when passing the spur. For more than one stroke of the bell to each revolution more spurs will be applied. y

We claim- 1. The combination of the central stationary shaft 1', stationary fioor e, chambers f and 6, above and below said floor respectively, hollow shaft w surrounding the stationary shaft, spider y and disk 0 carried by said shaft; the hollow shaft p surrounding shaft 00 and having a step-bearing on the hub of shaft on, spider n and annular platform I), carriedby said spider, and the bevel-wheels t, a, and pinion v in chamber g and gearing said shafts with the driving-shaft substantially as described.

2. The combination of the central stationary shaft a, hollow shaft m surrounding said stationary shaft, hollow shaft 1) surrounding and having a step-bearing on shaft 03, spiders n and 3 carried on said shafts p and a: respectively, carrying-rolls z and e supporting said spiders respectively, radial axles and collars, and the rings controlling said rolls said spiders having the rails running on the rolls all substantially as described.

3. The combination of the stationary shaft 1', detachable sleeve 'm surrounding said shaft, wheel t having its support on the bed-plate, hollow shaft 13 having a step'bearing on the hub of said wheel 6, spider '11 carried on shaft 19, annular platform Z) supported by standards 0, on said spider, bevel-wheel u on sleeve 1), said wheels 25, and u geared with the drivingpinion Q) for turning reversely to each other, the hollow shaft extending upward within shaft 19 and surrounding sleeve m, the spider 3 mounted on said shaft m above spider n, and the disk 0 mounted on said spider n in the plane of annular platform I), all constructed and operating substantially as described.

Signed at Brooklyn, in the county of Kings and State of New York, this 3d day of May, A. D. 1895.
